Martino could have signed one defender he doesnt have to buy the best defender in the world like silva there are many other defenders who are much better than ours and they are not that expensive . I understand that our shit board doesnt want pay much money to a defender but at least buy on or two defenders who sont cost much. It wont kill us to buy someone who isnt that famous and dont cost the world.
People always think the grass is greener on the other side. "Martino could have signed one defender he doesnt have to buy the best defender in the world like silva there are many other defenders who are much better than ours and they are not that expensive" like who, please do tell. Even Agger is not that much of an improvement over Pique and he'll cost you over 35M euros.
People think just because you sign a CB Barca are going to magically stop allowing goals, just like that. That type of simplistic view is very annoying.
Solid CBs are needed, no doubt, however even if you bring Thiago Silva and David Luiz right this very second, guess what, Barca will still get caught on counters and Barca will still allow goals.
Barca have taken the first step to solidifying the defense, and that was to return the high pressing. You've already seen a much more solid defending performances on the first 3 official games without actually upgrading any spot.
If you really want to substantially upgrade the defensive side, I put it to you that upgrading both wingbacks would yield significantly better defensive results than upgrading both CBs.
